Veronica plant named &#39;tickled pink&#39;

ABSTRACT

A new and distinct  Veronica spicata  cultivar is provided that is well suited for providing attractive ornamentation in flower gardens. The plant is free-flowering and forms attractive bubblegum pink-colored racemes. A vigorous semi-prostrate growth habit is displayed. Durable long ovate to lanceolate leaves are formed. The plant commonly flowers on a substantially continuous basis from early July to mid-September.

VARIETAL DENOMINATION

cv. ‘Tickled Pink’

SUMMARY OF THE INVENTION

The new Veronica Plant (i.e., Spike Speedwell plant) of the present invention was discovered during 2003 at Holly Hill Farms, Earlville, Md., U.S.A., while growing among a population of plants of the Veronica spicata ‘Goodness Grows’ cultivar (non-patented in the United States). This new plant is believed to be a spontaneous whole plant mutation of unknown causation of the ‘Goodness Grows’ cultivar, and displays a distinctive blossom coloration together with a low growth habit. The new plant has been carefully preserved and evaluated in view of its distinctive combination of characteristics. Had the new cultivar not been discovered and preserved, it would have been lost to mankind.

It was found that the new Veronica spicata plant of the present invention displays the following combination of characteristics:

(a) exhibits a vigorous semi-prostrate growth habit,

(b) is free-flowering and forms attractive bubblegum pink-colored racemes,

(c) forms durable long ovate to lanceolate leaves, and

(d) is well suited for providing attractive ornamentation in the landscape.

The new cultivar well meets the needs of the horticultural industry and can be grown to advantage as a perennial garden plant to provide colorful ornamentation. For instance, it can be grown in front of borders, in rock gardens to provide a cascading effect, and in hanging baskets.

Plants of the new cultivar can be readily distinguished from other Veronica spicata cultivars including its parent. More specifically, the ‘Goodness Grows’ cultivar forms dark blue blossoms instead of blossoms having the bubblegum pink-colored coloration of the new cultivar.

The ‘Minuet’ (non-patented in the United States) and ‘Alba’ (non-patented in the United States) low-growing cultivars also display different characteristics. These cultivars along with the new cultivar commonly grow well in U.S.D.A. Hardiness Zone Nos. 3 to 8. The ‘Minuet’ cultivar forms dissimilar grey-green foliage, forms longer flowers of approximately 10 to 15 inches in length, and commonly stops blooming in late Spring. The ‘Alba’ cultivar forms dissimilar white flowers that are longer and commonly measure approximately 15 inches in length, and commonly blooms only in June and July.

The rooting of cuttings beginning in 2003 has been used to asexually propagate the new cultivar at West Grove, Pa., U.S.A. Rooted liners can be produced in approximately 30 days, and mature fully-grown flowering plants can be produced in approximately 25 weeks in 1 1/2-liter containers. It has been found that the characteristics of the new cultivar are stable and are reliably transmitted from one generation to another. Accordingly, the new cultivar can be asexually reproduced in a true to type manner.

The new cultivar of the present invention has been named ‘Tickled Pink’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the new cultivar in color as nearly true as it is reasonably possible to make the same in color illustrations of this nature. The plants were grown in containers at West Grove, Pa., U.S.A.

FIG. 1 illustrates a specimen of a typical mature flowering plant of the new cultivar wherein the semi-prostrate growth habit is apparent.

FIG. 2 illustrates a closer view of the flowers of the new cultivar in various stages of development.

DETAILED DESCRIPTION

The following is a detailed description while observing fully-grown plants of the new cultivar during the spring approximately 25 weeks following the rooting of cuttings. Such plants were grown in containers under greenhouse conditions at West Grove, Pennsylvania, U.S.A. The chart used in the identification of color is the R.H.S. Colour Chart of The Royal Horticultural Society, London, England. Common color terms are to be accorded their customary dictionary significance.

Disease Resistance

No particular resistance to pathogens and pests common to Veronica plants has been encountered during observations to date.

Plants of the ‘Tickled Pink’ cultivar have not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotypic expression may vary somewhat with changes in light intensity and duration, cultural practices, and other environmental conditions.
